Only if he has a DAT. Umm, no. Better recordings or different music. No such thing as stage when it comes to subs either...unless of course you have them in a stereo pair up front.Those processors aren't meant to restore bass or reconstruct bass, they are meant to add bass where it doesn't exist. Confusing to me why you'd want bassless music with bass. And OP, why even add an EQ or replace your HU? "Clean up" is not something an EQ can do. If you have an anomaly to tame or pull down then perhaps. Most people fall into the more adjustments is better and end up with worse sound. I knew your reply would be attacking mine lol. There's reasons why some people modify music. They feel there should be more bass in certain songs or mid or highs..... I've come across numerous songs where I didn't like how they were mastered. Highs and lows. Better recordings? Most anything you download now is 320kbps or 256kbps sample rates. To go beyond that, you need the original format which isn't always available. That being said, 320kbps is fine for most people, which most people can't even hear the difference between 256 and 320, I believe I do and the difference from 320 to lossless. Also, substage has been adopted as a term just like SQL has. They're both there, they're both commonly used so deal with it. So ummm, yes, more substage if you want more out of certain songs. That's why I use an LC-1.
